Humidity Control?

[Delphinus]

I run a dehumidifier but it's not enough -- on a cold night my windows will get serious condensation. I evaporate a solid 5g per day amongst all my current tanks so it's a serious issue for me.

I'm now having an HRV put in (just signed the papers this morning in fact). Myself (and a couple others from Calgary) had the work done by Air Pro Heating. I don't know if there's one in Edmonton but I must say I highly highly recommend these guys. Did a fabulous analysis and engineering approach to the amount of turnover required balanced against volume of evaporation, volume of my (eventual) tank room, volume of turnover for the rest of the house, etc.

Actually if you read the specs on HRV's -- I think I would consider getting one even if I didn't have fish tanks.
